Couplings

Designed for all types of polyethylene ducts, Aluminum Couplers feature a ribbed external surface that provides excellent non-slip gripping during installation. Their low profile allows the couplers to pass easily through plowchutes.

Anodized coating

Designed for all types of polyethylene ducts

Reverse-threaded couplers are tapered to accommodate a wide range of sizes and diameters

BARBED COUPLING

This innovative coupling design combines the advantages of low cost, reliability, and a fast time saving method of installation. Each of the barbed rings functions as a separate full circumference seal providing double protection against air passing through the connection.

The sharp precision cut barbs bite into the body of the duct creating a connection having both high internal and external sealing capability and exceptional pull out strength. Sealing and tensile efficiency of the couplings actually improves as internal air pressure in the duct increases during the cable placement operation. These coupling are also made for every size of SDR and SIDR innerduct.

Being a compression type fitting, the coupling must be pushed onto the innerduct under a compression load sufficient to cause the barbs to bite into the duct which requires the use of a hydraulic or mechanical coupling presses. A mechanically assisted installation procedure insures each coupling is installed properly, thereby, increasing the overall reliability of every connection.

2-Piece Couplings

This series of reusable air-tight molded couplings was introduced specifically to replace expensive two piece removable metal couplings. The couplings are injection molded of a UV protected glass fiver reinforced nylon, and underground applications with today's blown fiber technology. The couplings are reusable, removable, lightweight, seal completely to 200 lbs. psi.. The coupling body, rubber gasket and stainless steel fasteners are essentially impervious to corrosion. No special tools are required to install the couplings except a battery powered or hand held nut driver.

E-Coated Split-Lock Coupler

A split aluminum coupler with a black E-Coating for superior corrosion protection from road salts. Used mostly with air-assisted systems such as an Air-Trak. The coupler is reusable and is ideal for temporarily coupling conduits; particularly at slack-loop locations. The coupler is assembled using a 7/16" nut driver or or IA 552 PR Palm Ratchet. An IA 552 DAV Duct Assembly Vise is used to hold the coupler during assembly to permit easy, one-operator installation. Certain sizes UL Listed for use with HDPE and PVC for underground, above-ground or premise (indoor) applications.

Reround Coupling

Our tubing and pipe coupling is designed for permanent installation in the joining of either plain end, threaded, grooved or a combination of any of these joints. The band type construction holds the entire surface of the joint in uniform compression.

Couplings are made of heavy-gauge zinc-plated steel…prices of aluminum or stainless-steel couplings quoted on request.

Gaskets furnished standard in red rubber or black neoprene…please specify. Gaskets also available in white neoprene and a variety of other materials at a slight extra charge.
